APPARATUS FOR DRAWING FIBERS.

SPECIFICATION forming part of Letters Patent No. 461,855, dated October 27, 1891.

Application filed June 2 '7, 18 91.

To all whom it may concern.-

Be it known that 1, WILLIAM THOMPSON, a subject of the Queen of Great Britain, resid in g at Lark field, Rawdon Leeds, in the county of York, England, have invented a certain new and useful Improvement in Apparatus for Drawing Fibers, (for which I have obtained a patent in Great Britain under date of September 4, 1889, No. 13,913,) of which the following is a specification.

My invention relates to improved apparatus for the drawing of fibers, it being specially applicable for dealing with fiber of short stapie; and it may be used in combination with a mule or a spinning-frame, or the fibers so drawn may be twisted from theimproved appliance direct.

The improved apparatus consists of a series of suitable rollers over and under which are passed two endless bands, preferably of indiarubber or elastic band or web, which work one over the other, so as toconiine and carry the fibers between them until arriving at the delivery end,when they are diverted by guiderollers so as to separate or open the bands for the delivery of the fibers, the bands returning to the leading-in or starting rollers. The studded rollers may be of metal or hard Wood and may be provided with top or weight.

ing rollers.

I have obtained satisfactory results from the use of cog-wheels together with the elastic bands; butI prefer the studded rollers, as first mentioned.

To clearly explain my invention, reference is made to the accompanying drawings, in which Figure 1 is a side elevation of my apparatus. Fig. 2 is a front elevation. Fig. 3 is a crosssection on the line a: m of Fig. 2. Fig. 4 is an enlarged view of part of two of the rollers and bands. Fig. 5 is a section showing a modified form of roller. Fig. 6 is a detail View of a further modification.

The end frames 1 1 carry in drop-bearings the axles of the three studded rollers 2 3 4, which are geared together by the gears a b 0, carried by the axles, the roller 3 being adjustable by means of the strap 5, in which it rests, which strap maybe moved up and down by means of the screws 66. The two rollers 7 and S are guide-rollers, over which Serial No. 397,685. (No model.) Patented in England September 4, 1889, No. 13,913.

passes the endless band 9, said band also passing over the studded surface of the roller 3. The second band 10 passes over the studded surface of the rollers 2 and 4 and over the roller 3. The gears a b c are so arranged that the roller 3 is caused to travel faster than the roller 2 and the roller 4 faster than the roller 3, the elastic band 10 stretching to allow of this between the rollers 2 and 4 and returning to its normal tension when passing over the guide-roller 11. In this way the requisite drawing out or drafting of the fibers is attained through the variaton of the surface speeds of the roller-bands 9 and 10. The fiber is entered between the roller-bands at the guide-roller 7 and its exit is at the guideroller 8. It will be obvious that the draft may be varied as the surface speed of the two endless bands is changed. Either single bands 9 and 10 may be employed or a number traveling over the same rollers, as shown in Fig. 2.

The studded rollers 2 3 4: may consist of studs or pins 12, driven or otherwise fixed around the circumference of the roller; or a roller covering of wire cards set in a felt or other thick foundation may shown in Fig. 5; but I do not confine myself to any special form or kind of pin, so long as the rollers 2 3 4: are provided with studded, spiked, or porcupine surfaces; nor do I confine or limit myself to the use of three of such rollers, though I prefer the same, as a lesser or greater number may be employed.

In some cases, as in Fig. 6, I employ stud or cog wheels, the pitch and foundation of the teeth being such as to permit the cogs to partly gear, though covered by the india-rubber or other elastic sheet covering, around the teeth and which is by one tooth stretched and forced in and between two teeth of the other wheel, so that by the use of same I secure for particular fibers the desired short draft-that is to say, as the fiberis carried down between the teeth it is elongated or drawn out, according to the depth and foundation of the teeth on the wheels employed.
